The heart region electrically connecting the atria and ventricles; it slows the conduction of the depolarization wave so that a short period of time is interposed between atrial and ventricular contractions.
The AV Node is specialized conducting tissue that acts as an electrical road or gate connecting the atria to the ventricles. Normally the AV Node is the only electrical connection between these heart chambers. See Overview.
A group of cells located between the atria (upper two chambers) and the ventricles (lower two chambers) that regulates the electrical current (heart rhythm) that passes through it to the ventricles.
